A recent study found that about half of women diagnosed with early-stage breast cancer considered having a double mastectomy and one in six had the surgery, including many women who were at low risk of developing a second breast cancer. Medical Director of Breast Surgery, MemorialCare Breast Center at Orange Coast Medical Center, Jane L. Kakkis, M.D., discusses double mastectomies, including when they are necessary, benefits and risk factors, and what to expect before, during and after the surgical process.
